help! assembler errors.

[Andrei Cociuba]

i have a pic12f675 controlling a motor. the motor has a separate isolated controller.
one pin drives the motor one way
the other pin drives the motor the other way.
the motor spins a wheel via a gearbox and a rubber band.
the wheel has two sensors: one goes high when the wheel is turned to maximum, the other when it is to minimum.

the code:
#chip 12F675, 4
#config MCLRE = Off, Osc = Int 'Turn off MCLR, select internal osc.

#DEFINE turnon GPIO.0
#DEFINE turnoff GPIO.1

dir gpio in

main:

gosub initialize
epread(1,maxsteps)
limit = maxsteps / 2
for counter=1 to limit
gosub stepon
next

goto main

initialize:
'first turn everything off
dir turnoff out
set turnoff on
wait 5 s
set turnoff off
dir turnoff in

'read input state
gosub readstate

'count steps to full on, starting when lower switch is released
do until empty=0
gosub readstate
gosub stepon
loop

steps=0
do until full=1
gosub readstate
gosub stepon
steps=steps+1
loop

'write steps from empty to full into eeprom
epwrite(1,steps)
steps=0

dir turnoff out
set turnoff on
wait 5 s
set turnoff off
dir turnoff in
curstate=0
return

readstate:
full=gpio.2
empty=gpio.3
return

stepon:
dir turnon out
set turnon on
wait 50 10ms
set turnon off
dir turnon in
curstate=curstate+1
return

stepoff:
dir turnoff out
set turnoff on
wait 50 10ms
set turnoff on
dir turnoff in
curstate=curstate-1
return

the errors:

Looks like the Sourceforge team tackled the code tag problem already.  The new forum features are like a breath of fresh air.

Mostly  a syntax thing going on with the code. If using a symbol with a semicolon, then a goto is going to be expected, like:

    Main:
    mysub  ;or use call mysub
    …
    …
    goto Main

GCBasic is looking for something a little different for defining subroutines, like:

    sub mysub
    …
    …
    end sub  ;or use return if you like

Generally speaking, one woulldn't want floating inputs, so best just to define those needed to start with, even if you change them later.  If you set internal pullups on, or have pull down/up resistors, then no problem. 

    dir GPIO b'001100'  ; make GPIO.2 and GPIO.3 inputs
